Ruthless Rihanna they call her.

The “Rude Boy” songstress sat alongside her “Ocean’s 8” co-stars on Friday’s episode of “The Graham Norton Show”.

When sharing stories about the Met Gala Norton told Rihanna, Helena Bonham Carter, Sandra Bullock, Cate Blanchett and Sarah Paulson, “I presume you’ve all been to the real Met Gala.”

Everyone answered yes, except for Carter who revealed she had in fact never attended the highly exclusive fashion event. Carter’s “Ocean’s 8” co-stars all turned their heads in surprise. “You haven’t?” several of the actresses exclaimed.

“No,” Carter reiterated. And then Rihanna chimed in, telling Carter “that’s because you wear dresses like that,” while pointing at her outfit.

Rihanna’s playful shade drew laughter from Norton, the live studio audience and all of her fellow “Ocean’s 8” actresses. “That’s right, that’s entirely right,” Carter teased. “I am going to cry now.”
